These lenses are the latest generation of pinhole TV lens technology.
They provide high resolution and high fidelity images with very little
distortion to picture quality. They can see an entire room through
a hole less than 0.15 inch. These lenses are designed to work with
1/3", 1/4" and 1/5" format CCD cameras. Most of these pinhole lenses
work with either 12mm or C/CS mounts to accommodate miniature and
standard size CCTV applications. Focal lengths range from 2.5mm to
70mm ensuring that any covert surveillance application can be met.
